Across the nation people have protested in several big cities for weeks regarding two grand jury decisions to not charge police officers who recently killed two men in unrelated incidents.

On Thursday and into early Friday, the New York City Police Department arrested 223 people in overnight protests, opposing a grand jury’s decision not to indict officers in the choke hold death of Eric Garner, ABC News reported.

Thousands chanted “I can’t breathe,” the same words that Garner repeated moments before he was choked to death, and carried mock coffins with the names of people recently killed by police officers.
